How to correctly make an API request with a list of hostnames in the item.get method?

Question

Zabbix

Hello.
There was a desire to receive raw data from zabbix according to the list of host names
, a solution was previously found if the list of id host is submitted to the input

zabbix_get=\
    {
        "jsonrpc": "2.0",
        "method": "item.get",
        "params": {
            "output": "extend",
            "hostids": [123, 234],
            "search": {
                "key_": "vfs.fs.size"
            },
            "sortfield": "name"
        },
        "auth": authToken.get("result"),
        "id": authToken.get("id")
    }

tried by name of one server

zabbix_get=\
    {
        "jsonrpc": "2.0",
        "method": "item.get",
        "params": {
            "output": "extend",
            "host": "server01"
            "search": {
                "key_": "vfs.fs.size"
            },
            "sortfield": "name"
        },
        "auth": authToken.get("result"),
        "id": authToken.get("id")
    }

OK.
tried list

zabbix_get=\
    {
        "jsonrpc": "2.0",
        "method": "item.get",
        "params": {
            "output": "extend",
            "hosts": ["server01","server02"]
            "search": {
                "key_": "vfs.fs.size"
            },
            "sortfield": "name"
        },
        "auth": authToken.get("result"),
        "id": authToken.get("id")
    }

connection to Zabbix hung...
What did I do wrong and how to solve this problem?

Answer 1

Hello.
Didn't read / didn't read the API documentation carefully . The item.get
method does not have a hosts parameter . Also pay attention to the "Type" column, which indicates what type this or that parameter can take. For example, hostids can take an array or a string, while host can only take a string.
There are several solutions.
1. Use hostids array in params (as in your first example).
2. Use a filter with an array of host elements in params :

"params": {
  "filter": {
    "host": ["server01",
    "server02"],
    "key_": "vfs.fs.size"
  }
}
